Hello Ryan,
I made this lesson long time ago and I am thinking about remaking a new one with more information.
Anyway, you can say
“そちらの８１０の部屋に滞在している〜〜さんにつないで下さい。”
= Sochira no happyaku juu no heya ni taizai shiteiru (your friend’s name) san ni tsunai de kudasai.
or
810号室に泊まっている〜さんにつないで下さい。”
= Happyaku juugou shitsu ni tomatte iru ~~ san ni tsunai de kudasai.

Could you do a lesson on “texting”? I hear that phone email is used in Japan instead of texting. Here in the U.S., texting is constant for teenagers. I was wondering if a student should say, “tomodachi to keitai meeru o shimasu” to mean “I text with my friends.” Would that sound normal?

Hi sensei. Is it possible that sensei could explain this sentence for me a little?

1) また、終わらせないことで相手にどうしたらいいのか言ってもらう時間を与えることがあります。）

I feel it says something like: “Also, by not finishing what you want to express, you give the other party time to decide how to continue (make a follow up, how to proceed). As you can see Maggiesensei, I have a little problem with the “dou shitara ii no ka” in this sentence.

We sometimes give some time to the listeners to tell us what to do by not finishing the sentence.

So imagine you call me and ask me if Yukari is home. If I say
「Yukari は今、おりません。」
That is the end of the conversation. It may sound a bit strong unless you follow right away「何かご伝言はありませんか？」

But if I say
「Yukariは今、おりませんが….」
This unfinished sentence with “が” implies “What would like to do? What would you want me to do? Would you call her back later?”
Then you can think “Um.. what should I do. I will call her back then.”
Thus I can give you sometime to decide what to do without asking you to call her back.

I got it. I relate these types of sentences to something like: “He is not here now…” with the dots as to allow the other party to finish and unfinished or opened sentence.

What interested me the most from that previous sentence sensei is that I recently became aware of this type of usage of “ka” within a sentence. How should I put it? It is like a question that is not really a question but when you try to explain something. For example a sentence as this “what we need to do is to climb that tree.”

Actually I am not sure if I get the usage of “ka” when applied in this manner, that is why I asked the previous question. ^^’

Sorry for not explaining myself correctly sensei. Is it possible to give some examples of the usage of “ka” in this manner?

In this case, ~ からだったりして is a colloquial way to say (ひょっとして）~からかもしれない
In that short dialogue, they see someone was calling on Hiro’s cell phone and Hiro wondered it could be Ryoko who is calling.
涼子からだったりして。
Maybe it(the phone call) could be (from) Ryoko.

Compared to 涼子かもしれない(Maybe it is from Ryoko) , 涼子からだったりして has a connotation that “It would be strange/funny if this call is from Ryoko.)”

I understand your explanation and it really suits the circumstances of the conversation but I didnt know this use for -tari suru, it’s usual? I thought -tari suru is for listing activities that doesnt have a continuation or correlation, to mark an action as an example, the repetition of an action or the alternation of states.

So if he didnt just use kamo as the coloquial of kamoshirenai is to give that other connotation?
And why did you put hyotto shite in brackets? it’s because it’s usually obviated or it’s because it’s an alternative?
Sorry for the questions and thank you so much again <3

You are right.
Usually ~たり is used when you list up a couple of actions.
Ex. 寝たり食べたりする = netari tabetari suru = sleeping and eating etc.

〜たりして is a colloquial hypothetical word.
The translation is the same as かもしれない (maybe, may, might) but 〜たりしてinvolves more emotion, it would be surprising (fun, strange, great, awful) if ~ . You leave the sentence unfinished. So the listener has to read between the lines.

****
かも／かもしれない is just a statement.
1) 明日は雨かも（しれない）= I think it may rain tomorrow.
2) 明日は雨だったりして = What do you say if it rains tomorrow. (slightly less possibility than (1))
Also ~たりして shows more feelings.

***
Your other question :
（ひょっとして） 〜かもしれない
You add ひょっとして when you emphasizes the presumption/supposition.
